Help with XML/XSLT Formula

I am trying to come up with a formula for my XSLT Stylesheet that will return a result for the following:

If Column A is Equal to or Less than Column B, then = 0, but If Column A is Greater than Column B then calculate the difference (Column A - Column B).

I am completely lost! Any help would be greatly appreciated.

Here's a solution for you. If want to learn it yourself look at xsl:variable and xsl:choose from XSLT reference.

XML file I used:

Code:

 <?xml version="1.0" encoding="ISO-8859-1"?>
<calc>
<value1>2</value1>
<value2>1</value2>
</calc>

And the XSL transformer:

Code:

<?xml version="1.0" encoding="iso-8859-1" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.1">
<xsl:template match="calc">
<html>
<body>
<xsl:variable name='test' select='value2 - value1'/> 
<p>The value is:
<xsl:choose>
<xsl:when test='$test = 0'>
0
</xsl:when>
<xsl:when test='$test < 0'>
0
</xsl:when>
<xsl:when test='$test > 0'>
<xsl:value-of select='$test' />
</xsl:when>
</xsl:choose>
</p>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

Hope this helps, just remember to use < for smaller than instead of the normal '<' sign. Forum shows it as '<' even though it's really the escaped '<'...
